I am 100% that the entire song is correct,
the chords are a bit hard but keep at it and it shall work :)
| Four strokes inside this |
Intro: | Dm Dm/C | Bb13 A7+5 | Play four times
Verse: | Dm Dm/C | Bb13 A7+5 | Dm Dm/C | Bb13 A7+5|
| Gm7 | Bb13A7+5 | Dm Dm7 | Dm6 Dm7 |
| Bb13 | A7+5A7 | DmDm/C | Bb13 A7+5|
This is the basic layout of the song, play the intro once between every verse.
